Understood. That makes sense. In fact, your problem is most likely *not* related to this commit. As I mentioned before, please try narrowing down what specifically caused this; if I read correctly, you jumped from 2.6.33 to 2.6.36-rc1. There have been several important changes between those releases. Notably, this commit may be giving Samsung chips problems: 426c457a3216fac74e This thread is covering a few problems with Samsung: http://lists.infradead.org/pipermail/linux-mtd/2010-August/031590.html > And when I go further and put a JFFS2 in that partition and boot the > board I have > Despite these errors I can actually use the board (no kernel panic)! > The part is Samsung K9F1208U0C - PCB0 Unless you really know what you're doing, I wouldn't be writing/erasing the flash if it's not detecting bad blocks properly. Let me know if you have trouble with narrowing down to the problem commit. Brian
